Functional Analysis of Long Fiber Polyester Spunbond Needle Punched Geotextile

Long fiber polyester spunbonded needle-punched geotextile (referred to as geotextile) is an important material in the field of modern civil engineering, which is widely used in soil reinforcement, river treatment, foundation engineering and other aspects. Geotextiles play a vital role in engineering because of their unique physical and chemical properties. Below we will introduce in detail the function and application of long fiber polyester spunbond needle-punched geotextile.

Composition of long-fiber polyester spunbonded needle-punched geotextile
Long-fiber polyester spunbonded needle-punched geotextile is mainly made of long-fiber polyester material, which is processed by spunbonding process and needle-punched technology. This material has good strength, wear resistance, corrosion resistance and UV resistance, and can adapt to various harsh environments.

Main functions of long-fiber polyester spunbonded needle-punched geotextile
1. Reinforced soil: Long-fiber polyester spunbonded needle-punched geotextile has good tensile strength, which can effectively strengthen the soil and improve the carrying capacity and stability of the soil. In foundation engineering, it can be used to strengthen the structure of soil and prevent soil erosion and landslide.
2. River regulation: In the treatment of surface water bodies, long-fiber polyester spunbonded needle-punched geotextile can be used to make slope protection and bank protection structures to effectively prevent water erosion and protect river banks.
3. Separation and filtration: Geotextile has good permeability and filterability and can be used for soil separation and filtration. In water conservancy projects, it can be used in drainage systems to effectively remove water from the soil and improve the stability of the project.
4. Anti-seepage and water-stop: Long fiber polyester spunbond needle-punched geotextile can be made into impermeable membrane to prevent moisture penetration. In water conservancy engineering, underground engineering and other fields, it can effectively prevent water infiltration and protect the safety of the project.
5. Protective effect: Because the geotechnical fabric has good wear resistance, corrosion resistance and ultraviolet resistance, it can be used as a protective layer to protect the engineering structure from the external environment.

Application of Long Fiber Polyester Spunbond Needle Punched Geotextile
Long fiber polyester spunbond needle-punched geotextile is widely used in soil reinforcement, river treatment, foundation engineering, water conservancy engineering, underground engineering and other fields. For example, in foundation engineering, it can be used to enhance the soil structure and improve the bearing capacity of the foundation; in river treatment, it can be used to make slope protection and bank protection structures to prevent water erosion; in water conservancy projects, it can be used in Drainage system to improve the stability of the project.
